Hi, I was using Proxy Server 2.0 on Win2K, then I upgraded it to ISA Server with all its customise settings. Even then I can browse and access to other services sitting on ISA Server(interactively). After sometimes later I had to reinstall my ISA Server, now I am following these problems, 1. When I tried to restore the setting which I backed up before uninstalling the previous one, it did not restore by giving an error of mismatching type. 2. I was able to use Internet before now I cannot, as it tries to do but does not able to go. Can anybody tell why it is like this, OR it is by default that ISA Server blocks all traffic using it interactively. Thanks in Advance brain
